BARREL on KEG.

f -To alluiho'ni il may Concern way of handling barrels withoutliability of u loosening the joints and causing leakage,

Generally stated the invention comprises a barrel or like receptaclehaving closed ends and formed in two or more sections with theircontiguous ends provided with fianges and connected by means of a iingoi'hoop iiular key forced into said groove and keying the anges to saidgrooved ring, as will hereinafter be more fully described and claimed.

In the accompanying drawings Figure l lis a view partly in sideelevation and partly in section of one form of my improved barrel; Figs.2,-3', 4 and 5 are sectional detail views illustrating the method ofconf necting said bai-rel sections; Fig. 6 is a similar viewillustrating a modific'ationiii the shape of the connecting parts; Fig.T 1s a sectional detail of a portion of a barrel having longitudinalcorrugations and a flat plain bilge portion, and also showing a furthermodification ofthe connecting parts;

Fig. 8 is a sectional detail-illustrating an:

other form of the joint; and Fig. 9 is a transverse section through acompleted bar rel having sections connected as shown in Fig. 8. i f

The barrel shown 'is formed of a plurality of transverse sections l andl, which preferably areformed by stamping, pressing or spinning the samefrom sheet metal. The heads 2 are integral with the end sections,

and preferably are depressed Within the'ends of the shell as shown andare-(lished or coiicave. It is also preferred that the rim portionsconnecting the head with the shell be. curved and stand away from theshell, as such construction permits the. head to yield when 'subjectedto a severe blow, pressure or other stress. 4

Thevsections 1 and la are connected to- Specification of Letters Patent.

gethei' by lthe followinoP sents a l'ioop'or ring paced inside of thebariel and provided in its outer face with a groove 4 which may beformed therein either by cutting or rolling., The hoop or ringpreferably is continuous and without a joint or seam, but if desired itinlay be formed in sections. The contiguous edges of the sections l andl are flanged inwardly as ai T, 'said flanges entering the `groove 4. ofring` 5, and in the, preferred forni as shown i`n l ig'.

S,are provided with lips or projections T which lie in thel bottoni'ofgroove i and overlap one of said lips preferably at its free edgeforming an outwardly projecting -flange as shown'in Fig. S. "lhe flangesT are keyed into the lgroove l of ring 5 by means of'an unbroken annulusor ring tf, which is forced tightly into said groove to entirely fillthe saine and securely lock the' flanges in the groove. t Preferablythis ring or aiinnlus is'first heated and contracted peripherally andforced down into the groove. and isiioii-resilient so that when forcedinto the groove it takes a permanent. 4set and remains firmly in theposition to which it` is forced. It inay be contracted peripherally intothe groove 4 by any suit- .able ineaus and made to conform to the shapeof the groove in the ring. The groove 4 in ring or hoop 5 may haveflared walls as shown :in Figs. 2 to 5, oi' undercut Wallsl as shown inFig. 6, or parallel or right angled walls as shown in Figs. 'Tand S.When the key is Wedgeshape, as in Figs. 2 to ,5, and forced between theflangesT it serve4 to firmly press said flanges againstthe wallsI ofgroove Ll. vIn the forni shown in Figs. 1 to T the simple flanges 7 inaybe of such depth that they do not extend entirely to the bottom of thegroove el in ring or hoop 5 sothat small spaces ai'e left into whichsonie of the metal of the'key 6 is forced to holdI the -latter firmly inposit-ion, as shown in Figs.- 5, 6 and 7. To insure the spreading of themetal iiitothese spaces a V-shaped prothereof as shown) in Fgxj2.'Another-.see tion i'sthen lslidonto th'eprojecting .petition of the ringor hoop and the edge of this section is then bent down into the grooveand agaiilst the other sidewall thereof as shown in Fig'. 3. into thegroove between the turned-in parts T of the. shells or sections.

With the forni of flanges shownin Figs. l to T packing may be employedto prevent leakage, such packing preferably being placed between theflanges 7 and the.. side walls of the groove et, as shown at 9 in Fig.7. lVhen the flanges are provided with overlapping portions as shown inFig. .8 of practically the width of the groove, the key when it isforced inwardly, and particularly when it shrinks on cooling, tightly`forces the overlapping parts 7a together and against the bottom of thegroove so that an absolutely tight joint is provided. This form also hasthe advai'itage that if the barrel be given a blow endwise, such as whenslid down skids, the joint will not readily loosen, due to the fact thatthe overlapping portions 7 are substantially of the width of the groove,extend entirely across the groove and abut against the wall on theopposite A side of the groove, so that endwise shocks or blows on thebarrel have no effect on the joint.

lVhen the Vsections of the barrel or other receptacle are corrugatedlongitudinally, it is preferred that a portion of the barrel at itslargest diameter be left plain, as shown at 10, Fig. 7, so that thebarrel will roll easily. This plain portion is formed forcing the-netalat the ends of the adjoining sections outwardly, so that said plainportion forms the largest diameter or bilge of the barrel. The recessformed by so forcing out the metal toform this plain bilge, provides aseat for the hoop or ring 5.

It will be readily understood that the flanges 7 may be turned in beforethe hoop or rmg 5 is inserted. ln such case the hoop or ring should benoncontinuous so that its ends can vbe moved ont of line and its-dialneter sufliciently contracted to permit it being inserted into thesections.

rl`he barrel described is light and yet strong and capable ofwithstanding all ordinary usage. It is of standard barrel shape, thatis, enlarged at `the middle so that it can be readilyhandled, andparticularly easily up-ended. The joint can be made absolutely tight,and in the preferred form is of such a nature that it effectuallyresists end shocks.

The key (S is then forced .l barrel constructed as described can be usedfor storing and transporting even very mobile and volatile liquids.

What I claim is:

l. A barrel or other receptacle composed of a plurality of transversesections, contiguous ends of the sections being provided with inturnedflanges, and means for connecting se 'd sections consisting of anannular hoop or ring arranged within the sections` and grooved for thereception of the flanges of the latter, and a. continuous unbrokennon-resilient annular key contracted peripheral-ly and completelyfilling the groove in the ring and the space between the flanges.

A barrel or other receptacle composed of a plurality of transversesections, contiguous ends of the sections being provided with inturnedflanges and overlapping lip portions, an internal ring provided with agroove :For the reception of said flanges and lips, and a continuousunbroken non-resilient annular key contracted peripherally into thegroove in the ring and between the flanges and forcing the overlappinglips into contact.

3. A barrel or other receptacle composed of a plurality of transversesections, an internal ring grooved on its outer face, contiguous ends ofsaid sections being provided with inturned flanges having at their edgesoverlapping lips supported in the groove of. said ring, and an unbrokenannulus contracted peripherally into said groove between the flanges andforcing the overlapping portions into tight Contact with each other andwith the bottom of the groove. l

et. A barrel or other receptacle composed of a plurality of transversesections, an internal ring grooved on its outer face, contignous ends ofsaid sections being provided with inturned flanges and with lips ofsubstantially the width of the groove in said ring, the lips of the twosections overlapping in said groove and a continuous unbroken annularkey contacted peri'pherallyinto said groove between the flanges of thesections and forcing the overlapping lips into tight. contact witheachother and with the bottom of the groove.

ln testimony4 whereof, I have hereunto set my hand.
